Abstract
Within this work, field observations of structure and intensity of motor transport streams were conducted, the information about the operating sources of atmosphere pollution from the enterprises in the city of Naberezhnye Chelny, their qualitative and quantitative structure, physical parameters were collected, processed and systematized. On the basis of the obtained data a summary calculation of emissions of the industrial enterprises and motor transport was carried out, the list of the priority polluting substances was defined, the complex index of pollution of the atmosphere was calculated, highways with the greatest transport loading were defined. On the basis of instrumental control the measurements of quality of atmospheric air near highways were carried out, actions for optimization of transport streams and decrease in negative impact were offered.
Highlights
Nowadays the problem of studying of ecological state of the cities gains the increasing concern
If emissions of the industrial enterprises are the subject to rationing, the organization of transport streams is generally reduced providing the greatest capacity of the city highways and the set of ecological factors aren’t considered
In order to estimate the atmospheric air of the city and define the places of the greatest concentration of the polluting substances according to the methods (Milyaev, et al, 2000; Recommendations, 2002; Settlement instructions, 2008; Suleymanov, Mavrin, & Harlyamov, 2011a; Suleymanov, Mavrin, & Harlyamov, 2011b; Suleymanov, Mavrin, & Harlyamov, 2011c; Suleymanov, et al, 2013; Suleymanov, G., Mavrin, & Mavrin, V., 2014; Suleymanov, Mavrin, & Harlyamov, 2012; Suleymanov, Mavrin, & Makarova, 2013) calculations of emissions of mobile sources were made
Summary
Nowadays the problem of studying of ecological state of the cities gains the increasing concern. Actuality of this kind of research is dictated by a need of protection and rational use of environment and preservation of a favorable ecological situation. In the cities with the developed industry the share of a contribution of automobile exhaust gases makes about 50-70% of cumulative emissions of the polluting substances. If emissions of the industrial enterprises are the subject to rationing, the organization of transport streams is generally reduced providing the greatest capacity of the city highways and the set of ecological factors aren’t considered
